FAQ
Questions about this model.
What link distance is listed for the 100G QSFP28-SR4 100Gb/s 850nm MPO-12 Multimode Fiber Optic?
The listed reach is 100 m. Actual distance depends on the installed fibre loss, the number of connectors and splices and the receiver sensitivity at both ends, so confirm the optical budget for your own path before ordering. Our link budget calculator works through the arithmetic in a minute.
Which wavelength does this module use?
It is listed at 850 nm. Both ends of a duplex link must use the same wavelength plan.
What connector and fibre does it need?
The listed interface is MPO-12 on Multimode Fiber (MMF). Check that your patch cords, panel adapters and polarity match before installation.
Does it support DDM / DOM diagnostics?
Listed as: Yes. Digital diagnostics report optical transmit power, receive power, bias current, supply voltage and module temperature through the host, which makes commissioning and fault isolation far faster than swapping parts.
Is an industrial temperature version available?
The listed operating temperature is 0 ~ 70°C. Commercial (0~70°C) and industrial (-40~85°C) grades can be quoted; state the installed environment in your inquiry so the right grade is offered.
Can it be coded for my switch?
Yes. Send the host manufacturer, the exact model and the software version with your inquiry. Coding is confirmed per platform before production — a connector that fits does not by itself prove the host will accept the module.
Can I evaluate a sample first?
Include the required quantity, host platform and destination in your inquiry. Sample availability, charges and lead time are confirmed in the quotation, and we recommend testing in the intended port before a bulk order.
